(Cl. 248-354) This invention relates to new and usefulimprovements in supports or jacks particularly, although notnecessarily, for house trailers or mobile homes and has for its primaryobject to provide, in a manner as hereinafter set forth, novel means forexpeditiously leveling, firmly supporting and laterally stabilizing suchvehicles.

. Another very important object of the present invention 18 to provide asupport which may be adjusted readily to meet various conditions, suchas uneven or inclined ground, etc.

Other objects of the invention are to provide a mobile home support or.jack of the character set forth which will be comparatively simple inconstruction, strong, durable, compact, of light weight and which may bemanufactured at low cost.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

Figure 1 is a view in end elevation of a mobile home support or jackembodying the present invention, showing the device in use;

Figure 2 is a view in side elevation thereof; and

Figure 3 is a perspective view of one of the units, showing a portionthereof broken away in section.

Referring now to the drawing in detail, it will be seen that theembodiment of the invention which has been illustrated comprises a pairof upwardly and inwardly inclined duplicate jack units which aredesignated generally by the reference character 4. The units 4 includespaced, parallel, inverted V-shaped bases 5 in the form of angle bars ofsuitable metal. Fixed at longitudinally spaced points on the bases 5 areupwardly and inwardly inclined sockets 6. Telescopically adjustablescrew jacks 7 are mounted in the sockets 6. The jacks 7 include threadedlower male sections 8 which are engaged in the socket 6. The jacks 7further include smooth upper female sections 9 which are slidablyadjustable on the lower-sections 8. Nuts 10 are threaded on the lowerjack sections 8 for adjusting the upper sections 9 and securing the samein adjusted position. The pairs of screw jacks 7 are connected byanglebar heads 11 on the upper ends of the sections 9. The heads 11 areengageable longitudinally with the lower edges and outer sides of theusual sills or frame members 12 of a trailer 13.

Fixed on intermediate portions of the bases 5 are hinge plates 14comprising inwardly projecting knuckles 15. Angulated levers 16 ofsuitable fiat metal are mounted for vertical swinging movement on thehinge plates 14. The inner end portions of the levers 16 comprisefurcations 17 which terminate in knuckles 18 aligned with the knuckles15. Pins 19 in the knuckles and 18 pivotally connect the levers 16 tothe plates 14. Between the furcations 17, the levers 16 further comprisespaced, reversely bent hooks or lugs 20.

The units 4 are adjustably and detachably connected by crossed chains21. The chains 21 have one end portion fixed to the heads 11 atintermediate points by welding, as indicated at 22. The other endportions of the chains 21 are inserted between and engaged with thehooks or lugs 20 for adjustably and detachably connecting said chains tothe levers 16.

It is thought that the use of the device will be readily apparent from aconsideration of the foregoing. Briefly, the heads 11 are engaged withthe frame members 12 of the trailer 13 and the bases 5 are placed on theground, as indicated at 23, in approximately the position shown therebydisposing the jacks 7 at an upward and inward inclination. The nuts 10are then tightened to secure the adjustment. The levers 16 are thenswung upwardly and the free end portions of the crossed chains 21 areconnected thereto. The levers 16 are then swung downwardly pastdead-center for tightening the chains 21 and clamping the heads 11 onthe trailer frame members 12 in an obvious manner. Of course, anydesired number of the devices may be used beneath the trailer. When thechains 21 are tightened the heads 11 function as jaws which grip thetrailer frame members 12 therebetween.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalentsmay be resorted to, falling within the scope of the invention asclaimed.

What is claimed as new is as follows:

1. A vehicle support and stabilizer comprising: a pair of unitsincluding spaced bases to be positioned beneath the vehicle, upwardlyconvergent jacks on said bases comprising heads on their upper endportions engageable with the vehicle, crossed braces connecting theunits for preventing the bases from spreading, and means for tighteningsaid braces, said means including levers hingedly mounted on the basesand connectible to one end portion of the braces. 7

2. A vehicle support and stabilizer comprising: a pair of unitsincluding spaced bases to be positioned beneath the vehicle, upwardlyconvergent jacks on said bases comprising heads on their upper endportions engageable with the vehicle, and means for drawing the headstoward each other on the vehicle and for preventing the bases fromspreading, said means including crossed chains having one end afiixed tothe heads, and levers hingedly mounted for vertical swinging movement onthe bases,

said levers including members adjustably engageable with" the other endportions ofthe chains for operatively connecting said levers thereto.

3. A trailer support and stabilizer comprising: a pair of unitsincluding spaced, parallel, elongated bases to be positionedlongitudinally beneath the trailer, pairs of upwardly convergent jackson said bases, elongated heads connecting the upper ends of said pairsof jacks and engageable with the trailer, and means for clamping saidheads in engagement with the trailer and preventing the bases fromspreading, said means including crossed chains having one end fixed tothe heads, and levers hingedly mounted on the bases and operativelyconnected to the chains for tightening the same, said levers beingswingable past dead-center for securing the chains taut.

4.. A trailer support and stabilizer comprising: a pair of duplicateunits including bases comprising spaced, parallel, inverted V-shapedbars to be positioned longi-.

tudinally on the ground beneath the trailer, pairsof up? wardly andinwardly inclined sockets on said'bars, up wardly convergent pairs ofscrew jacks mounted in said aeroso s sockets, angle bar heads connectingthe upper ends of the pairs of jacks and adapted to receive the trailerframe therebetween and engageable therebeneath, and means for drawingthe heads together on the trailer frame and for preventing the basesfrom spreading.

5. A trailer support and stabilizer comprising: a pair of duplicateunits including bases comprising spaced parallel, inverted V -shapedbars to be positioned longitudinally on the ground beneath the trailer,pairs of upwardly and inwardly inclined sockets on said bars, upwardlyconvergent pairs of screw jacks mounted in said sockets, angle bar headsconnecting the upper ends of the pairs of jacks and adapted to receivethe trailer frame therebetween and engageable therebeneath, and meansfor drawing the heads together on the trailer frame and 15 2,924,463

for preventing the bases from spreading, said means including crossedchains having one end anchored to the heads between the pairs of jacks,and levers hingedly mounted for vertical swinging movement on the basesbetween said pairs of said jacks, said levers including means adjustablyengageable with the other end portions of the chains for operativelyconnecting said levers thereto.
